[Asterisk-Users] which channel format number is right?
Hi all,
if i enter a "show codecs" at cli * response with:
1 (1 << 0) G.723.1
2 (1 << 1) GSM
4 (1 << 2) G.711 u-law
8 (1 << 3) G.711 A-law
16 (1 << 4) MPEG-2 layer 3
32 (1 << 5) ADPCM
64 (1 << 6) 16 bit Signed Linear PCM
128 (1 << 7) LPC10
256 (1 << 8) G.729A audio
512 (1 << 9) SpeeX
1024 (1 << 10) iLBC
65536 (1 << 16) JPEG image
131072 (1 << 17) PNG image
262144 (1 << 18) H.261 Video
524288 (1 << 19) H.263 Video
If i enter a "show channel" * response with
Name: H323/ip$XXX.XX.XX.XX:3520/25650
Type: H323
UniqueID: 1068111809.487
Caller ID: <0109901>
DNID Digits: (N/A)
State: Ringing (5)
Rings: 0
NativeFormat: 8
WriteFormat: 8
ReadFormat: 8
1st File Descriptor: 366
Frames in: 0
Frames out: 1240
With wich codec is the channel working now, with ALAW or with g.729A ????
And what is the relevant value "read/write format" or
"nativeformat" ?
Thanks for help,
Thomas.
